3 1 Introduction This manual provides guidance for use of Gasmaster PC software. To install Gasmaster PC insert the disk into the CD drive of your PC; the software should begin the installation process automatically. Follow the instruction shown and re-start your PC when the installation sequence is complete. To enable configuration of Gasmaster panels, connection to a PC can be made using a serial cable and RS-485 to RS-232 converter (Crowcon part number C01929). A communications port is fitted to Gasmaster as an option to allow simple connection. If the Gasmaster panel does not have a communications port fitted, a serial cable can be connected to the RS485 TERM terminals on the terminal PCB fitted inside the unit. 2 Initial configuration Upon initial installation, no configuration data will be available. If Gasmaster PC is run with no Gasmaster connected the display screen would resemble the image shown below. To allow the system to be initialised, an auto system configuration sequence is started. This takes the form of a Modbus address locator which will search for any Gasmaster units connected to the PC. November

4 2.1 Auto System Configuration Auto system configuration is performed only when the Gasmaster PC application cannot find configuration information on the PC on which it is being run. On start-up, the application will check for the configuration of a system and if not found, automatically begins a system scan to configure Gasmaster PC according to Gasmaster panels connected to the PC. This configuration takes the form of a screen that enables the user to scan the system for attached instruments. The Com port list will show all free ports detected on the PC. Click to select the appropriate Comm port (ie the port to which the Gasmaster is connected) and click Start Scan to begin the scanning process. When one or more Comm ports are selected, then the Start Scan button will become active. This action will begin the scan process and show a progress indicator as shown on the next page. November

5 The user is given the ability to cancel the operation on a per port basis. This allows the user to shorten the time spent on the address scan if they know that all addresses reside within a specific range. On Completion of the scan, the locator screen will be updated to show all instruments found within the addresses scanned by the Modbus Locator. These will be shown in a list of addresses that are selectable by the user (see below). November

6 At this point, the user may select a particular Gasmaster to connect to by clicking the appropriate box in the Address list and then clicking Add. Alternatively the user may re-scan the system using the start scan button. On selecting an item in the Address list, the Add button becomes active. After a short period the screen will change as shown in Section 3 below. 3 System Configuration After adding a Gasmaster as described in the previous section, or when running the software at any time other than the initial run, a previously saved configuration will be loaded into the Gasmaster PC Tree. To connect to a Gasmaster panel simply click the relevant icon; the customer ident will be the system name saved on the Gasmaster unit (Test Unit in this example). The configuration will be loaded from the saved data and items checked to ascertain that they still exist on the system. Each configured Comm port will be checked to verify whether the Comm port still exists on the system, and each configured Modbus address will be checked to locate an instrument at that address. If either the Comm port or Modbus Address does not exist, then the items are simply not shown in the tree. In the event that this fails to provide a valid instrument on the system, then a dialog will be shown to the user informing them of this fact, and the user must perform a manual system scan to refresh the system. November

7 3.1 Manual System Scan If no Comm ports are listed, the PC system can be scanned to detect available ports. Right clicking on the tree port node with the mouse and selecting the scan port item performs this task. 3.2 Manual Port Scan The manual tree configuration also allows the user to re-scan a specified port by right clicking with the mouse to access the port menu. Each Gasmaster panel has a Modbus node address, and it is this address which is searched for by Gasmaster PC. The default address set by Crowcon during manufacture is 1. Selecting the scan Modbus addresses item will re-scan the whole of the selected port for connected Gasmaster units. 3.3 Add Modbus Address The user is also able to add a single specified address on the port if required. This enables the user to enter the specific address of a Gasmaster unit without scanning the port. Selecting Add Modbus address will display an input box that accepts numeric input in the range of 1 to 247. Entering an address will cause the application to check the validity of the specified address (i.e. by checking that a Gasmaster with the address is connected), and if valid, will add the address to the tree. November

8 Specifying an address for which no Gasmaster is connected will prompt the following message to be displayed Could not find instrument at specified address. 3.4 Remove address Right clicking with the mouse on an instrument node will present the user with the remove menu item. Selecting the remove item will show the user a confirmation dialog, and on accepting, will remove the instrument from the tree. 4 Instrument Mimic Display Selecting a Gasmaster panel using the icon on the tree will display a mimic which represents the current operating state of the unit. Information on this screen is constantly updated and any new alarms and faults will be shown as they occur. November

9 Details of any system faults or warnings will be shown in the appropriate dialogue boxes. Alarm, fault, warning and inhibit icons will light automatically should the status of any input channel change. 5 Instrument Configuration Selecting Configuration on an instrument node in the tree will load the configuration from the Gasmaster unit and display details as shown below. The configuration screen allows the user to load a configuration file, edit the configuration, and write the configuration to the instrument. Major functionality is performed through the toolbar located at the top of the work area. 5.1 Toolbar The toolbar allows the user to perform major functionality through a single mouse click. The buttons from left to right consist of Read from Instrument, Write to instrument, Load from File, Save to File, Load Language, Print Configuration, and Set Supervisor Password. November

10 Read from instrument Selecting this button will allow the user to read from the selected Gasmaster. A message box will be shown to the user informing them that the current configuration will be overwritten, and asking if they want to continue or not. Write to instrument Selecting this button will allow the user to change the Gasmaster settings by writing the configuration shown on screen to the instrument. This function is password protected. The user must enter the correct supervisor password to write to the instrument. If the password is entered correctly, then the password will not be required again whilst the user remains in the configuration screen. The default password is GASMASTER. Load from File Selecting the load from file button will display the following screen: This function enables the user to search for configuration files stored on the PC, ready for modification and/or downloading to the connected Gasmaster unit. Save to File Selecting the save to file button will present the user with a dialog to enter a file name to save as, with full system browse capabilities to allow saving of a file in a folder of the users choice. The dialog will default to a folder specified in the options screen that is user customisable. Load language All Gasmaster units display information in English, but can have an alternative language loaded which will become the default language used for the display. Selecting the load language button will present the user with a wizard dialog to allow then to save language strings to file, and load languages from file. Navigation through the wizard is performed by the Next and Back buttons. The initial provides a choice of loading the language file from the Gasmaster or from a file. November

11 Download from instrument to file Selecting the download from instrument to file option, and clicking on the next button will move the wizard to the following screen: There are two fields available: November

12 Select a file to save OEM specific strings to : this will retrieve the distributor details from the Gasmaster as shown when the unit is powered-up and when the Gasmaster Back button is pressed on the normal operating screen. Standard units will display Service/Support: Crowcon +44 (0) The data will then be stored in the selected folder on the PC. Select a file to save non OEM specific strings to : this will retrieve the general second language display files from the Gasmaster and store them in the selected folder on the PC. Once one of the above options is selected, the back button becomes enabled, whilst the next button becomes disabled, the user may either manually enter a filename, or use either of the select buttons to open a file browser to select a file. Selecting an existing file will prompt the user to confirm a file-overwrite. Once either of the filename fields has data entered, the save button becomes enabled. Clearing the filename fields will disable the save button. Clicking on Save when enabled will write the language strings to the named file(s). Clicking back at a point prior to the save will return the user to the function selection screen. Upload from file to instrument Selecting the upload from file to instrument option, and clicking on the next button will move the wizard to the upload screen. This enables PC language files to be downloaded to a Gasmaster. There are two fields available: November

13 Select a file to load OEM specific strings from : this will load a.csv file from the PC containing local distributor details which can be downloaded to the Gasmaster for display when the unit is powered-up and when the Gasmaster Back button is pressed on the normal operating screen. Standard units will display Service/Support: Crowcon +44 (0) Select a file to load non OEM specific strings from : this will load a.csv file from the PC containing the translated Gasmaster display strings, and download them to the Gasmaster. Files can be written to the Gasmaster by clicking Load once the file-paths described above have been entered. A password will be requested at this point; the default password is linguist. To enable the secondary (translated) language to be displayed on the Gasmaster select the Secondary option in the Language field on the configuration display (see section 5.2 for details). Print Configuration Selecting the Print Configuration button will send the current configuration to a printer in a pre-set format. The printed specification uses information contained in a file called Printer.txt. If this file is not present an incomplete certificate will be printed. The file is located in the folder Documents and Settings\All Users\GasmasterII\Certificates Change supervisor password This function allows the Gasmaster PC supervisor password (required to download configuration changes to the Gasmaster) unit to be changed. The default password is GASMASTER. To change the password, enter the current password in the top field, and the new password in the middle and lower fields. Press OK to confirm the change. November

14 5.2 Configuration Screen The configuration screen allows the user to change the configuration of the connected Gasmaster. Note: the following terms are used to describe options for audible/visual alarms and alarm/fault relays: Latched means that in an alarm state, the output will stay active when the Accept/Reset key is pressed, and will only reset when the alarm or fault has cleared and the Accept/Reset key is pressed again. Non-latched means that in an alarm state, the output will stay active when the Accept/Reset key is pressed, but will reset automatically when the alarm has cleared. Latching acceptable means that in an alarm state the relay will reset when the Accept/Reset key is pressed (even if the hazard is still present). Non-inverted means that a relay coil is not energised in a non-alarm state (normally de-energised). Inverted means that a relay coil is energised in a non-alarm state (normally energised or fail-safe ) A description of the function of each field follows: System Fields: Serial Number This is a sixteen-character field that holds the serial number of the connected Gasmaster instrument.
